Can you put soy meat in a crock pot?

i don't think so because i think it will over cook the soy crumbles. i've cook them too long it reminded me of chewing on bits of pencil erasers. they were rubbery. when i cook them for a short period of time and used them they were texturally fine. maybe pan fry them and then add them a 1/2hr before chili is finished? i've always fried mine first, i hate nuked soy products because of the texture.
